Speeiiication forming part of Letters Patent No. 54,842, dated May 22,1866; antedated May 16, 1866.

To all whom it may concern:

Be it known that I, FRANCIS M. BIRDSALL, of Martinsville, Clintoncounty, and State of Ohio, have invented a new and useful Improvement inFurrowing Out Machines, of which thefollowing is a full and cleardescription, reference being had to the accompanying drawings, formingpart of this specification.

My invention relates to a simple device by means of which the plows maybe drawn toward the center of the machine when it is neccssary to passthrough a narrow passageway, and also to secure the plow above theground.

Figure l in the accompanying drawings is a plan of myimprovedfurrowing-out machine. Fig. 2 is an elevation ot my improved machine.

`A represents the trame of the machine, which is secured to axle-tree aby means et' two standards, which are secured to axletree a..

b is the seat. At either end ot' seat b are boxes c, in which arepivoted the levers d. Levers d are attached to the plow-frames e byChains or other flexible materialf. A series of furrowin g-plows, g, areattached to the lower extremity ot1 plow-frames e.

The longitudinal strips e ot' frames e are hinged at their forward ends,c, to sliding strips 7i, which move freely side by side upon the top ot'the trame and tongue oi" the machine. They are held in place by thecentral strap, i, which is made fast to the tongue and side strips, lr,which are attached to frame AA.

Rods Z prevent from spreading the frame e. Check-bars m are designed tosecure the levers Z when plow-frames e are elevated at their back ends,in order to throw the plows g out ot' and above the ground. n aredrag-bars to which double-trees or single-trees may be attached.

Operation: When it is necessary, on account ot obstructions or duringthe disuse, the plow may he removed from and above the ground bydepressing the front end of levers d, which are secured by passing overthem the checkbars m.

In furrowing out for the planting' ot' corn or other grain, the plowsare equidistant. The plow-frames are prevented from too great lateralspreading by rods Z. When it is necessary to pass the machine Vthrough anarrow gateway the plow-frames may be pushed in towardv the center ofthe machine, as shown in Fig. l, contracting the width of the machinewithin the usual limits.

Having fully described my furrowing-out machine and the operation of itsvarious parts, I make the following claim n The plow-frames e,longitudinal strips e', and levers d, in combination with plows g, frameA, and sliding strips It, constructed as above described, and for thepurposes setforth.
